Facebook Offers lets businesses offer coupons and specials to fans through posts that appear in people’s news feeds on both desktop and mobile, as well as through posts that are promoted as sponsored stories. Fans will be able to redeem Offers via email or on a mobile device.

(Facebook Offers is not to be confused with Google Offers, the search giant’s Groupon competitor.)

The difference seems to be that between 2010 and today, mobile has become a much bigger deal for Facebook. For years, the social network didn’t sell ads on its phone app; Facebook began rolling out mobile ad units in February.
